/**
 *
 * Basis Data Export
 *
 * Utility that exports and saves sensor data from the Basis web site.
 * You can learn more about Basis at http://www.mybasis.com/

 * Modified by @author Leonard Ng'eno
 * 
 * Usage:
 * 
 * This script can be run several ways.
 *
 * [Method 1] Via interactive mode
 *   a. Open a terminal window and cd to this script's directory.
 *   b. Type php basisdataexport.php
 *   c. Follow the prompts (hit ENTER to use default values)
 *   d. Your data will be save to /data/basis-data-[YYYY-MM-DD].[format]';
 *   
 * [Method 2] Via command-line arguments (useful for crons)
 *   php basisdataexport.php -s[YYYY-MM-DD] -e[YYYY-MM-DD] -f[json|csv]
 *
 *   Options:
 *   -s  Data export start date (YYYY-MM-DD) (if not used, defaults to yesterday's date)
 *   -e Data export end date (YYYY-MM-DD) (if not used, defaults to today's date)
 *   -f  Data export format (json|csv) (if not used, defaults to json)
 *   -h  Show this help text
 * 
 *  You can edit the BASIS_EXPORT_FORMAT value so you don't have to specify it every time the script is run. 
 *  Make sure the data/ folder is writeable.
 *  Enter the basis usernames and passwords in the users.csv file. Enter each pair on its own line
 *  and use commas to separate the username from the password field.
 *
