This class create a single mosaicked image from a set of images.
The set of input images are all assumed to be in the same coordinate space. In general, all the images must have the same resolution; differences that are within a small epsilon or exactly a power of two are optionally allowed.

The parameters to this function mirror those of the constructor: this function will return LT_STS_Success if and only if the images' resolutions are such that a mosaic can be produced.
imageStageManager | manages the set of input images |

Creates an image stage which is a mosaic of the set of input images.
In order to create a mosaic, the ground resolution of all component images must match exactly or be offset by a power of two. For example, two images having 1m resolution can be mosaicked with an image having .5m resolution. However, an image with 1ft resolution will cause an error condition. Slight variations in resolution will be automatically tolerated to accommodate differences in floating-point representation.
The "useMultires" flag will allow images to be mosaicked that do not have compatible ground resolution. Setting this flag will cause some images in the mosaic to be resampled to achieve compatible resolution.
Transparency settings are honored by the mosaic process.
