gitignore changed: Simulations folder added
changed classnames
sweep.m: problem fixed. Timestamps changed. simMultParam: lattice_type added
simAll returns Array of Qdot objects and success vector. checkSuccess Function implemented (not complete).
.gitignore: Simulation folder added. Renamed class DB again into DButils. Added Functions getEntries, getIndex (working), createMatrix (not complete), removeEmpty (not yet implemented). Removed functions delete, newEntry.
new gui_simulate, directly table to qdot
new gui_simulate
Qdot constructor: read default values from file. DButils: createMatrix enhanced.
fixed major problems. Table directly to  qdot.
init: automatic user recognition
Qdot constructor and default files
little changes in all classes
simAll: checksuccess function fixed
sweep: possible spherical geometries with an arbitrary number of materials. Voltages: For every Voltage specified by [Vdmin,Vdmax,NVD] an individual dot is crated (NVD =1). Stability of sweep.m not yet guaranteed.
tested and fixed sweep and simAll
Tested and verified Simulations of Sweep Params Radiuii and Voltage. simAll: checkSuccess fn: fixed some Bugs.
