Message:

Correcting a bug which sometimes make transformations between different size grids incorrect

+) Correct inputs of some functions
+) Add some auxilliary functions.
+) Add new test cases for test_remap

Test
+) Basic test pass
+) Single horizontal and vertical interpolation are correct
+) Chained interpolation are not correct
