compute_rdf: direct type label support

Browse Source 
type label that is the same as the keyword ('cutoff') will break things. if syntax is otherwise 'correct', then will throw a syntax error. perhaps could run through typelabels to check first?

listed, then a separate histogram is generated for each
*itype*,\ *jtype* pair.
The *itypeN* and *jtypeN* settings can be specified in one of two
ways. An explicit numeric value can be used, as in the fourth example
above. Or a wild-card asterisk can be used to specify a range of atom
types. This takes the form "\*" or "\*n" or "m\*" or "m\*n". If
:math:`N` is the number of atom types, then an asterisk with no numeric values
means all types from 1 to :math:`N`. A leading asterisk means all types from 1
to n (inclusive). A trailing asterisk means all types from m to :math:`N`
(inclusive). A middle asterisk means all types from m to n (inclusive).
The *itypeN* and *jtypeN* settings can be specified in one of three
ways. One or both of the types in the I,J pair can be a
:doc:`type label <Howto_type_labels>`. Or an explicit numeric value can be
used, as in the fourth example above. Or a wild-card asterisk can be used

If both *itypeN* and *jtypeN* are single values, as in the fourth example
