Added support to return integer value.

[Sameer-Tilak]

This PR refer to issue #133.
Modified code to return value as integer if it is with General type and no decimal values or as number type with no decimal values (may need it as integer)

I've implemented similar functionality in #240, which includes type support for all cell types, not just integers.

Is your branch merged to master?

In new changes you have changed the return value. Earlier it was float and not you are returning sting. All existing code that is based on original gem will fail and will have to modify.
I tried to maintain the return value.

[stevendaniels]

The changes have not been merged into master yet.

#240 won't break existing code. The return values for cells remains the same for all types except for Boolean cells, which now return booleans instead of strings (see the test/test_roo.rb diff)

Your changes work for a subset of the type issues Roo has, but it doesn't solve the others. Additionally, your changes have some unresolved test failures.

Thanks for this pr. I'm closing due to #240.
