non-continuous element support

[cdeterman]

Previously users could only index single elements or contiguous regions for simple functions like read/write (e.g. bm[1:3,1:3]). These new changes allow users to index non_contiguous elements that mirror the normal R matrix/data.frame syntax for use cases such as bm[c(1,2,5)] or bm[c(2,4)] <- 42. Relevant unit tests have been added.

FYI, you may notice that coverage has decreased significantly but this is because coveralls is now also looking through all the C++ files as well as the R files.

Something actually seems off here, somehow coveralls isn't recognizing anything. I will keep looking into this. Everything still functions correctly though.

Please note that you could index non-contiguous subsets. You can not create a sub.big.matrix on a non-contiguous subset.

[cdeterman]

@kaneplusplus these changes aren't for subsets. They are just for access to individual elements. It was previously not possible to index a big.matrix object with a single argument (e.g. bm[3]) for the third element where you previously needed bm[3,1].

My mistake, thanks for the clarification.
