Enumerate tutorials and rebuild

[goggle]

I have renamed and rebuilt all the tutorials as suggested in #60.

Here are some problems, which I could not solve by installing the needed packages (I have not modified any of the *.jmd files in tutorials/ except of renaming them).

introduction/05-formatting-plots:
The line

plot(sol,vars=(:x,:y,:z))

leads to this error:

Error: MethodError: no method matching pointer(::Symbol)
Closest candidates are:
pointer(!Matched::String) at strings/string.jl:81
pointer(!Matched::String, !Matched::Integer) at strings/string.jl:82
pointer(!Matched::SubString{String}) at strings/substring.jl:104

models/06-pendulum_bayesian_inference gives some warnings when building with Weave.jl:

[ Info: Weaving chunk 8 from line 91
┌ Warning: seriestype density has been moved to StatsPlots.  To use: `Pkg.add("StatsPlots"); using StatsPlots`
└ @ Plots ~/.julia/packages/Plots/oiirH/src/args.jl:1061

I don't know if this is relevant...

ode_extras/01-ModelingToolkit: I'm unable to install PuMaS.jl:

using PuMaS
Error: ArgumentError: Package PuMaS not found in current path:
- Run `import Pkg; Pkg.add("PuMaS")` to install the PuMaS package.

import Pkg
Pkg.add("PuMaS")

ERROR: The following package names could not be resolved:
 * PuMaS (not found in project, manifest or registry)
Please specify by known `name=uuid`.

type_handling/01-number_types: There are two errors.

using DecFP
prob_ode_decfplinear = ODEProblem(f,Dec128(1)/Dec128(2),(Dec128(0.0),Dec128(1.0)),Dec128(1.01))
sol =solve(prob_ode_decfplinear,Tsit5())

gives

ERROR: StackOverflowError:

and

using Decimals
prob_ode_decimallinear = ODEProblem(f,[decimal("1.0")]./[decimal("2.0")],(0//1,1//1),decimal(1.01))
sol =solve(prob_ode_decimallinear,RK4(),dt=1/2^(6)) #Fails

gives

ERROR: MethodError: Decimals.Decimal(::Rational{Int64}) is ambiguous. Candidates:
  (::Type{T})(x::Rational{S}) where {S, T<:AbstractFloat} in Base at rational.jl:92
  Decimals.Decimal(num::Real) in Decimals at /home/alex/.julia/packages/Decimals/Qfcas/src/decimal.jl:13
Possible fix, define
  Decimals.Decimal(::Rational{S})

which seems to be somewhat expected from that #Fails comment.

type_handling/01-number_types gives two errors:
The line

t + sqrt(t)

results in

Error: DimensionError: 1.0 s and 1.0 s^1/2 are not dimensionally compatible.

And the code

using DifferentialEquations
f = (y,p,t) -> 0.5*y
u0 = 1.5u"N"
prob = ODEProblem(f,u0,(0.0u"s",1.0u"s"))
sol = solve(prob,Tsit5())

gives

Error: DimensionError: N s^-1 and 0.75 N are not dimensionally compatible.

Furthermore, I was unable to build the PDFs for the following tutorials because of LaTeX errors:

• models/03-diffeqbio_I_introduction
• models/04-diffeqbio_II_networkproperties
• models/06-pendulum_bayesian_inference
• models/07-outer_solar_system
  Is that something that should be reported to Weave.jl?

This PR looks messy... I think I will close it and open a new one.
I've just discovered that there is currently no Jupyter notebook for ode-extras/ModelingToolkit. Is there any reason for that?

Because I was at a conference when I made it so I rushed it lol
