<dt>Parameters:</dt>
<dd><code>nMarkers</code> - number of markers in the dictionary</dd>
<dd><code>markerSize</code> - number of bits per dimension of each markers
This function creates a new dictionary composed by nMarkers markers and each markers composed
by markerSize x markerSize bits. If baseDictionary is provided, its markers are directly
included and the rest are generated based on them. If the size of baseDictionary is higher
than nMarkers, only the first nMarkers in baseDictionary are taken and no new marker is added.</dd>
