    NAME
        zeq_magic.py

    DESCRIPTION
        reads in magic_measurements formatted file, makes plots of remanence decay
        during demagnetization experiments.  Reads in prior interpretations saved in 
        a pmag_specimens formatted file and  allows re-interpretations of best-fit lines
        and planes and saves (revised or new) interpretations in a pmag_specimens file.  
        interpretations are saved in the coordinate system used. Also allows judicious editting of
        measurements to eliminate "bad" measurements.  These are marked as such in the magic_measurements
        input file.  they are NOT deleted, just ignored. 

    SYNTAX
        zeq_magic.py [command line options]

    OPTIONS

        -fsp SPECFILE: sets pmag_specimens format file with prior interpreations, default: zeq_specimens.txt
        -Fp PLTFILE: sets filename for saved plot, default is name_type.fmt (where type is zijd, eqarea or decay curve)
        -crd [s,g,t]: sets coordinate system,  g=geographic, t=tilt adjusted, default: specimen coordinate system
        -fsa SAMPFILE: sets er_samples format file with orientation information, default: er_samples.txt
        -spc SPEC  plots single specimen SPEC, saves plot with specified format 
              with optional -dir settings and quits
        -dir [L,P,F][beg][end]: sets calculation type for principal component analysis, default is none
             beg: starting step for PCA calculation
             end: ending step for PCA calculation
             [L,P,F]: calculation type for line, plane or fisher mean
             must be used with -spc option
        -fmt FMT: set format of saved plot [png,svg,jpg]
        -A:  suppresses averaging of  replicate measurements, default is to average
        -sav: saves all plots without review
