Push a new mesh into the refinement system.
This is the first call user programs make into the refinement system. This call need *not* be repeated when the refinement system changes the mesh; only when the user changes the mesh (e.g., to coarsen it).
Conn is row-major, and maps an element number to three node numbers. Hence conn[i*3+j] gives the local number of node j of element i. Because of shared nodes, every node of every local element will be local. Ghost elements may not have the complete set of nodes-- some of their nodes may have the invalid number -1.
Elements with numbers between 0 and nEl-1 (inclusive) are local. Elements with numbers between nEl and nGhost-1 (inclusive) are "ghosts"-- elements that are actually local on another processor. There are guaranteed to be enough ghosts that every local element's non-boundary edge will face a ghost element.
gid maps an element number to a chunk number and local number on that chunk. These are stored at gid[i*2+0] (chunk number) and gid[i*2+1] (local number).
boundaries is the boundary flags for nodes. boundaries may be null, if the user doesnt specify boundary flags. nnodes specifies the number of nodes

Return one split triangle.
A and B are the nodes along the splitting edge:
C C / \ /|\ / \ / | \ / \ => / | \ / tri \ / | \ / \ /tri | new\ B --------- A B --- D --- A
The original triangle's node A should be replaced by D; while a new triangle should be inserted with nodes CAD.
The new node D's location should equal A*(1-frac)+B*frac. For a simple splitter, frac will always be 0.5.
If nodes A and B are shared with some other processor, that processor will also receive a "split" call for the same edge. If nodes A and B are shared by some other local triangle, that triangle will immediately receive a "split" call for the same edge.
Parameters: -splitNo is the number of this split. Pass splitNo in increasing order from 0 to REFINE2D_Get_Split_Length()-1. -conn is the triangle connectivity array, used to look up the node numbers A, B, and C. This array is *not* modified. -tri returns the number of the old triangle being split; as labelled above. -A,B,C returns the numbers of the nodes in the above diagram. -frac returns the weighting for D between A and B; for now, this is always 0.5.
Client's responsibilities: -Add the new node D. Since both sides of a shared local edge will receive a "split" call, you must ensure the node is not added twice; you can do this by checking this split's nodes A and B against the previous split. -Update connectivity for source triangle -Add new triangle.
