added transitDepth
mu now uses mass first than radius to determine type, mass type returns None if theres no mass value
reintroduced planetDict for referencing one target absolutely
when using .type() will default to massType, if no value will then use radiusType() (before if mass was empty it returned None)
transit time calculation assumes 90 degrees if i is nan
logy now correctly calculated with log10 not log (natural log)
updated mass type and temp type assumptions
added .transittime value
Merge branch 'release/1.0.6'
added magK
