8a19b719d6 when Reynolds number is zero, return zero friction factor 
which means there is not friction pressure loss. The formualtion has
problem in handling zero-value Reynolds number.

6366087efd using UMFPACK for the function invDX 
for better robustness.

The iterative solvers require more improvement.

78a28abf91 fixing a bug related to adding ms well during simulation. 
When there is not ms well involved, all the ms well related is not
initialized. It causes problem when we want to add ms well after some
time of running.

The bug fix the running with model 2.

6fb459a797 introducing tolerance_pressure_ms_wells for pressure equations 
for the multisegment wells. More detailedly, we should distinguish the
rate control equations, bhp control equations and ordinary pressure
equations.

dd9ad42a28 correcting the size of seg_comp_initial_ based on num_comp 
for standards wells, all the three equations are mass balance
equatiions, it is safe to use numWellEq.

for MS wells, there is one extra pressure equation, it should be the
number of mass balance equations. If we do not put the polymer equation
inside the well equations, we will face dilemma soon.

0dc041d46a adding a use_multisegment_well_ 
to determine whether we will treat mutlisegment wells with
MultisegmentWell well model. Currently, it will be faulse by default.
It might be changed to be true by default when considering the
multisegment well model is well tested.

3255626b2e scaling the gas rates a little bit for MS well. 
It can possibly benefit the StandardWell, while it is something needs a
little bit more investigation before using it.

c6be20c5cb copying the segment rates and segment pressure from old well state. 
It can be something rather tricky. It looks like with simple trival
initization, it is difficutl to converge. But when there is change to
the well, direct copying will not work anymore. Will we also facing
convergence problem?
