made all the wavelets a function of duration (time window) and sample interval (dt), and made LFM and Klauder one function (sweep)
change algos in energy.py and similarity.py to use duration (in sec) and sample interval in dt
changed the wavelets to match new APIs
fixed some renaming _alg
changes names in __init__
change lfm to sweep in __init__
took away compute_ name from attribute__init.py
one more removal of _compute
Modified to handle the case when the frequency input is a list
merged the new dir structure
