Matching DIC and EBSD after finding grains in a DIC map

[mikesmic]

The process of matching grains in a DIC to EBSD map needs to be made more robust or some error handling added so the process does not completely fail if match is not found. A typical error that can occur (noted by @dtfullwood, thank you):

---

IndexError Traceback (most recent call last) in () 66 ### Detect grains in the DIC map 67 ---> 68 DicMap.findGrains(minGrainSize=100) 69 DicMap.buildNeighbourNetwork() 70 # **************************************************

The DIC min grain size should correspond approximately to the EBSD min grain size. There should be a check of this. The EBSD step size is taken from the file and the DIC step size is defined manually, so should be easy to check.
