Returns the optimal battery size for an imported list of historical loads for a building.
Two ways to run it:
1. enter location of csv data file as a String that contains only meter reads, one on each row. Defaults to "data://MadDenker/LCTest1/LC2.csv" Default file contains hourly kWh reads for a small residential building.
2. enter a one dimensional array of double values. Ex: [1.25, 1.47, ...]
Output is the optimal battery size in the same units as the input.
