Detailed Description

Information on a single stretch of field within a Input XBar Byte, which comes from the P4 program, i.e. say the following was a key:

key { hdr.nibble1 : exact;  hdr.nibble2 : exact; }

where hdr.nibble1 and hdr.nibble2 are both 4 bit fields in the same Container Byte, i.e. H0(0..7). Then each P4 field would have a FieldInfo, and the Use::Byte would have a vector of two FieldInfo objects.
