Addition of mascara_utils.py that includes:
- readCurve: reads a raw light curve and returns a 2d numpy array with the data
- readData: reads a raw light curve and returns JD and raw flux
- getVMAG: gets the magnitude given a hip number
- plotCurve: plots the raw flux as a function of JD
- plotPosCCD: plots the position of the star on the CCD for all observations
- diagnoseCurve: makes plots for diagnostics purposes
- plotRMSvsVMAG: plots SNR of all light curves in a directory as a function of magnitude
- binData: bins the data (JD, light curve)
Added displayStamp method. The diagnoseCurve now allows the user to select a point on the light curve and see the corresponding post stamp
