ASCII file reader and handler

Functions

convertDepthThickness	convert depthField to thicknessField or the other way around depending on type, using a DEM to compute the slope angle required for transformation also writes field to a new directory called transformed where depthFile/thicknessFile is located
fetchPointValuesFromField	derive field values at xyPoints using a interpMethod (options: nearest and bilinear)
