(i.e. each point will not vary too far from its predecessor)

1 2	createRandTimeSeries(length, first, max.variability, embed, interval, floor, ceiling)

`length`	Numeric length of the time series
`first`	Numeric first value of the time series
`max.variability`	Maximum difference between any point and its predecessor
`embed`	A numeric vector that will be embedded within the time series
`interval`	A numeric time interval to be inserted between each point. This makes the time series regular.
