# Notes:
#
# This module utilizes personal Fitbit's user-specific API
# information to perform OAuth connection to Fitbit and submit the
# request for your heart rate data for any 24 hour period.
#
#
# Installation Instructions:
#
# Run the MSI installer or, if installing manually, copy the
# psFitb1t.psm1 and psFitb1t.psd files to:
# "%PSModulePath%psFitb1t"
#
# HINT: To manually create the module folder prior to copying:
# mkdir "%PSModulePath%psFitb1t"
#
# Once installed/copied, open Windows Powershell and execute:
# Import-Module psFitb1t
#
# Store your Fitbit API information by executing:
# Set-FitbitOAuthTokens
#
# If you have gotten this far, you should be able to query your
# first date by executing:
# Get-HRData -QueryDate "2016-01-01"
#
# Verification:
#
# Check "%PSModulePath%psFitb1t\Logs" folder for a daily rotating log.
# Example log for successful query:
