Added core.progress

Browse Source 
// core.progress returns an object with the following properties
//   total_blocks: the number of total blocks in the experiment
//  total_trials: the number of total trials in the experiment
//  current_trial_global: the current trial number in global terms
//      i.e. if each block has 20 trials and the experiment is
//     currently in block 2 trial 10, this has a value of 30.
//  current_trial_local: the current trial number within the block.
//  current_block: the current block number.

Useful for showing user progress through the experiment. Planning to add
an option to show a progress bar in the future.
