# BARlib.py
# IJ BAR: https://github.com/tferr/Scripts#scripts
#
# Common BAR library to be placed in BAR/lib. This file hosts methods to
# be used across all your scripts. To add these scripting additions, append
# the following to your Jython scripts:
#    import bar, sys
#    sys.path.append(bar.Utils.getLibDir())
#    import BARlib as lib
# Then, call functions as usual:
#    lib.confirmLoading()
#


##### Utilities #####
def confirmLoading():
    """Acknowledges accessibility to this file"""

    """Returns text from the system clipboard or an empty string if no text was found"""

def randomString():
    """Returns a random uuid"""
    import uuid

##### CALCULATIONS #####

            svalues[i] += values[j]; n += 1
        svalues[i] /= n
