Check whether file extension is as specified

Provides string arithmetic, reassignment operators, logical operators
that handle missing values, and extra logical operators such as floating point
equality and all or nothing. The intent is to allow R users to write code that
is easier to read, write, and maintain while providing a friendlier experience
to new R users from other language backgrounds (such as 'Python') who are used
to concepts such as x += 1 and 'foo' + 'bar'.
Includes operators for not in, easy floating point comparisons, === equivalent, and SQL-like
like operations (), etc.
We also added in some extra helper functions, such as OS checks, pasting
in Oxford comma format, and functions to get the first, last, nth, or most common
element of a vector or word in a string.
