fixed bug in run_writedataset causing file to always be written to bcilab/userdata
Merge branch 'master' of https://github.com/sccn/BCILAB
pop_epoch now iterates over (and epochs) all fields in EEG.tracking.timeseries_fields
added SIFT filter (flt_siftpipeline) to repository. this implements a SIFT pipeline
vis_filtered:  added numeric y-tick labeling for icaact and srcpot datafields. added custom 'ylabel' option to fcn arguments.
Fixed time-series field iteration in pop_epoch (and made compatible with older MATLABs).
Reworked ml_trainproximal to support multi-task losses; still needs to be tested.
Implemented set_concat to concatenate continuous-time data.
Doc fix in set_joinepos.
Doc additions to flt_delayembed.
Added the ability to list workspace approaches defined as cell arrays (in GUI).
More work on ml_trainproximal.
Fix in ml_trainvote.
Added ability to collect per-fold models in bci_train, utl_crossval, utl_evaluate_fold, and utl_nested_crossval.
Minor updates to ParadigmMKLCSP, ParadigmSSRCSP.
More work on ParadigmMSERP.
Merge branch 'master' of https://github.com/sccn/BCILAB into multitask
Added support for multiple frequency bands in flt_analytic_phasor.
Fixed minor parameter shape issue in flt_clean_windows.
Disabled warning related to set_concat (new function).
Updated flt_rej_impedance.
Fixed handling of event-free signals in flt_resample.
Updated flt_siftpipeline and flt_sourceLocalize.
Added frequency sampling option to flt_analytic_phasor.
Added ability to design odd filters to design_fir.
Updated flt_siftpipeline & dynamicLoreta (minor).
Fix in analytic phasor for multi-band case (chanlocs).
Fix in onl_filtered (typo during exception propagation)
Added flt_beamformer.
Reenabled some deprecated support for setting argsubtoggles to 0/false to turn them off.
Fixed an issue with set_insert_markers inserting a marker at latency 0.
Robustified set_selinterval to out-of-bounds markers.
Added support for buffered continuous-data operation to flt_siftpipeline.
Fixed the buffering in flt_siftpipeline.
Added flt_buffer to buffer data into fixed-size chunks for subsequent pipeline stages.
Fix in onl_peek.
Updated proximal splitting code (fixes for multi-task losses).
Fixed ParadigmMKLCSP (works now) and ParadigmMSERP (in development).
Merge branch 'multitask' of https://github.com/sccn/BCILAB into multitask
Doc refinements to arg_subtoggle.
Speeded up a bottleneck in flt_beamformer.
Added diagnostic message to flt_clean_channels.
Added missing randsample function to flt_repair_channels.
Updated flt_selchans to use the new utl_match_channels.
Fixed an oversight in onl_peek (would by default only pull one channel).
Added ult_match_channels (replaces prior use of eeg_matchchan).
Added small version of Montreal head model.
Fixed set_concat and set_joinepos for the case of empty events.
