### R3mCalculate ###

Authors: Kevin DeBoyace, Mustafa Bookwala
A function to calculate the molecular descriptor R3m.
This function calculates the molecular matrix (M), geometry matrix (G), molecular influence matrix (H), and influence distance matrix (R). This is accomplished by calling the following subfunctions: ImportSDF, MolecMatrix, EuclidDistance, MolecInfluenceMatrix, and InfluenceDistanceMat. This function currently only works for SDF files. Other file formats can be converted to SDF using OpenBabel. When the code is run, the user is prompted to select an SDF file. Next, the molecule is plotted using the PlotMolecule function to ensure the 3D coordinates are reasonable. Finally, the R3m value is calculated and output to the command window and workspace.

NOTE: The R3mCalculate function is the primary function. The other functions and scripts are referenced by this function. The user will only need to run the R3mCalculate function:
e.g. [R3m] = R3mCalculate;
