        #### Help(BitBin)
        ```
        Help on class BitBin in module bitn:
        
        class BitBin(builtins.object)
         |  BitBin(bites)
         |  
         |  Methods defined here:
         |  
         |  __init__(self, bites)
         |      From bytes to bits
         |  
         |  as90k(self, num_bits)
         |      Returns num_bits 
         |      of bits as 90k time
         |  
         |  asdecodedhex(self, num_bits)
         |      Returns num_bits of bits 
         |      from hex decoded to bytes
         |  
         |  asflag(self, num_bits=1)
         |      Returns one bit as True or False
         |  
         |  ashex(self, num_bits)
         |      Returns the hex value 
         |      of num_bits of bits
         |  
         |  asint(self, num_bits)
         |      Starting at self.idx of self.bits, 
         |      slice off num_bits of bits.
         |  
         |  forward(self, num_bits)
         |      Advances the start point 
         |      forward by num_bits
         |  
         |  rewind(self, num_bits)
         |      Rewinds the start point 
         |      back by num_bits  
         |  ----------------------------------------------------------------------
        
        ```
        
        
         I used to do this
        ```python3
           from struct import unpack
             
            sync,two_bytes,one_byte = unpack('>BHB', packet[:4])
            tei = two_bytes >> 15 
            pusi = two_bytes >> 14 & 0x1
            ts_priority = two_bytes >>13 & 0x1
            pid = two_bytes & 0x1fff
            scramble = one_byte >>6
            afc = (one_byte & 48) >> 4
            count = one_byte & 15
        ```
         Now I use bitn and do this
        ```python3
            from bitn import BitBin
            
            header= BitBin(packet[:4])
            sync=header.asint(8)
            tei=header.asflag(1)
            pusi=header.asflag(1)
            ts_priority=header.asflag(1)
            pid=header.asint(13)
            scramble=header.asint(2)
            afc=header.asint(2)
            count=header.asint(4)
        ```
        
        #### Example Usage
          *  Parse  a SCTE 35 splice information section from a hex encoded string
        
        ```python3
        
        >>> from bitn import BitBin   
            
        
        >>> bites= bytes.fromhex( 'FC302F000000000000FFFFF00506FEAEF17C4C0019021743554549480000077F9F0808000000002CA56C97110000C4876A2E')
        
        >>> class Splice_Info_Section:    
                def __init__(self,bitbin):
                    self.table_id =bitbin.ashex(8)
                    self.section_syntax_indicator = bitbin.asflag(1)
                    self.private = bitbin.asflag(1)
                    self.reserved=bitbin.asint(2)
                    self.section_length = bitbin.asint(12)
                    self.protocol_version = bitbin.asint(8)
                    self.encrypted_packet =  bitbin.asflag(1)
                    self.encryption_algorithm =bitbin.asint(6)
                    self.pts_adjustment = bitbin.as90k(33)
                    self.cw_index = bitbin.ashex(8)
                    self.tier = bitbin.ashex(12)
                    self.splice_command_length = bitbin.asint(12)
                    self.splice_command_type = bitbin.asint(8)
              
        
        >>> bitbin=BitBin(bites)
        
        >>> sps=Splice_Info_Section(bitbin)
        
        >>> vars(sps)
